Laser scar treatment uses light rays to partially damage collagen in scarred area. Then the body’s natural healing process sweeps away older, damaged tissue and rebuilds it with fresh, new collagen and elastin – the crucial building blocks of normal-looking skin.
Several different types of technology exist like Fractional CO2 laser, Fractional Erbium Glass laser, Microneedling RF. Basic principle is same in all these lasers.
